Waste treatment of remazol blue compounds based on ozonation/AOP in a bubble column reactor

Increased production in the textile industry has the potential to result in high dye waste water. Various conventional methods to handle with textile waste treatment have been done, but still considered not yet or less effective. The AOP technology (Advanced Oxidation Processes) applied in this research is a rapid degradation technology in textile wastes with advanced oxidation process through the formation of hydroxyl radical (OH) which is considered to optimize the degradation process of textile dye waste. This study aims to evaluate the performance of ozonation methods and AOP (O3/UV/H2O2) in dye degradation of textile wastewater containing remazol blue compounds. Both configuration methods used are optimized in several parameters such as waste flow rate, ozone voltage and pH to obtain maximum remazol blue degradation. From this study, the higher percentage to remazol blue degradation is 99.99%, which is achieved by AOP method, with double air injection air flow rate of 10 L/min and 0.25 L/min liquid flow rate
